Application fil d March 21, 1906. Serial No. 307249.

To all whom it may concern:

Be it known that I, ANTHONY Tom, a resident of Napa, in the county of Napa and .IIS

strains to which the structure may be sub-v j ected.

One object of the invention is to provide a cheap, efficient, and scientifically-construct-- ed truss whereby the least amount of metal consistent with strength will beemployed in the construction. Another-object of the invention is to ro- .vide an improved binder or stirrup which will form a support for the bars as well as a spacer. 4

A further object is to provide a stirrup made from a single rod and so formed that it will act as a carrier for the bars when first placed in position to receive the concrete.

Referring particularly to the drawings which illustrate this invention, Figure 1 is a and beam rovided with the reinforcement. Fig. 2 is a orizontal section on a line y y in Fig. 1. Fig. 3 is a transverse vertical section on a line a a: in Fig. 1. Fig. 4 is a similar section on a line 2 2. F ig.'5 is a perspective view of the stirrup, showing-cross-bars supported thereon,

As shown in the drawings, 1 and 2 represent the columns, and 3 the beam, of the structure. Running from the outer edge of said columns (speaking of two of them) are horizontal rods 4, bent downwardly at right angles, as at 5. Above these rods 'and resting upon them in the central part are arranged a corresponding number of rods '6, bent upward symmetiicall on each side of the center to a suitable height and then again horizontally running to a point above the end of the lower rods. Running at right angles to said rods are arranged horizontal rods 7, of similar shape as the rods 4, but preferably of smaller diameter and of varying length. The distance between the latter and the rods 4 is governed by the thickness of the.

beam and is kept constant by means of a stirrup 8, formed in the following manner: A rod of any suitable thickness and length is first bent in. the middle with a slight curve or bow 9, and the ends are each in the form of a hook 10. Then running obliquely upward to a point substantially equal in height to the 'bow a loop 11 is-formed parallel to the bow or .at right angles -to the plane of the book, then down again obliquely, but in the op osite direction, forming another hook 12, w ence it a ain runs upward substantially perpendiciilar and is then provided with a right-' angled bend 13 of the same height as the bow and loop and extending in opposite directions away from each other. In this manner a basket-shaped binder orstir'rup is formed of a single rod, which is ready to re ceive the tension and binding-rods, and the same are assembled in the following manner: A number of stirrups are placed in the boxes which receive and form the concrete. On account of their form the stirrups will stand unsupported on the bottom of the boxes, resting upon the four hooks 10 and 12v The rods 4 are then placed in the hooks and upon them, as already described, the rods 6. The cross-rods 7 are then placed in the loops 11, resting upon or preferably at the ends of the bows 9, but. passing under the bends '13. In this manner a substantially rigid connection is attained between the bars, and the concrete can be readily deposited in the boxes without displacing the reinforcements. V

Having described my invention, I claim 1. A new article of manufacture, a stirrup for concrete structures, consisting of a rod having its ends bent into hooks in two planes and each provided with a loop at the to standing at right angles to the planes.

2. A new article of manufacture, a-stirrup for concrete structures, consisting of a red bent into two hooks in two substantially parallel planes, each provided with a loop at the top standing at right angles to said planes and the free ends bent at right angles to the planes of the hooks and extending in opposite directions from each other.

3. A new article of manufacture, a stirrup for concrete structures, consisting of a rod,

the central portion of which is bent into a slight curve and the ends of which are bent downward. then obliquely upward to form a hook. then. into a loop at the top at right angles to the plane of the-hook, then ab IIO letewsillyat shbstanti'alll y iiht;ang1es' to.1he
